  • the driver hears and acknowledges this warning, judges the traffic conditions, and actuates operating means such as, for example, a throttle grip in the case of a motorcycle, to reduce the speed of the vehicle.
  • This warning is a not only an audible signal, but may also be a visible signal, such as the illumination of a display lamp.
  • response time is preferably shortened, but there is the limitation described above, and it is possible to fail to recognize the warning due to overlooking, misreading, not hearing, or mishearing the warning if the driver becomes flustered when hurrying.
  • the present invention has been conceived in view of the above points, and the object of the invention is to provide an information device that enables a substantial reduction in overall response time and makes it difficult to fail to recognize a warning.
  • the present invention provides an information device including an external force generating means for supplying an external force to an operating means touched by the extremities, the hands or feet, of a driver at the time of the operation of a vehicle; judging means for receiving an external signal and judging traffic conditions; and control means for controlling the driving of the external force generating means based on the determined results of the judging means.
  • the external force generating means is driven based on the result of the judgement and the external force is supplied to operating means touched by the hands or feet of the driver for controlling driving devices of a vehicle while the vehicle is travelling.
  • the present invention provides an information device wherein the external force generating means supplies external force to a throttle grip of a vehicle with handlebars.
  • the present invention provides an information device wherein the external force generating means comprises at least one of an urging means for supplying an urging force to the throttle grip in a direction to reduce the number of engine revolutions, and excitation means for supplying vibration to the throttle grip.
  • vibration is applied to the throttle grip to be actuated according to traffic conditions, and an urging force is applied in a direction to reduce the number of engine revolutions.
  • the driver recognizes the vibration or urging force directly acting on his hands, so there is no failure to recognize the warning and it is possible to significantly reduce the overall response time.
  • the present invention provides an information device wherein the external force generating means supplies external force to an accelerator pedal of a four wheeled vehicle.
  • the present invention provides an information device wherein the external force generating means comprises at least one of urging means for supplying a new urging force to the accelerator pedal in a direction to return to a deceleration side, and excitation means for supplying vibration to the accelerator pedal.
  • vibration is applied to the accelerator to be actuated according to traffic conditions.
  • An urging force is applied in a direction to reduce the number of engine revolutions.
  • the driver recognizes the vibration or a new urging force directly acting on his feet, so there is no failure to recognize the warning and it is possible to significantly reduce the overall response time.
  • FIG. 1 is a cross sectional drawing of a throttle grip 1 of a motorcycle according to one embodiment of the present invention.
  • FIG. 2 is a schematic block diagram of a control system for the information device motor drive.
  • FIG. 3 is a flowchart of the control sequence of the control system shown in FIG. 2 .
  • This embodiment is an information device applied to a motorcycle.
  • FIG. 1 is a cross-sectional drawing of a throttle grip 1 of a motorcycle.
  • the throttle grip 1 is a closed cylinder and is supported by being rotatably fitted onto the right side end of a cylindrical handle bar 2 .
  • the throttle grip 1 is urged in the direction of reducing the engine speed by a spring (not shown). Acceleration is controlled by a twisting actuation against the force of the spring.
  • a miniature motor 3 is fitted inside the left end of the handlebar 2 , a drive shaft 3 a of the motor 3 protrudes from an opening in the right side of the handlebar 2 .
  • the end of the drive shaft is attached to a centrifugal clutch 4 .
  • the centrifugal clutch 4 is positioned along the bottom wall of the inside of the throttle grip 1 .
  • the motor 3 rotates the drive shaft 3 a in the direction in which the throttle grip reduces the speed of the engine.
  • the centrifugal clutch 4 rotates in the same direction as the drive shaft 3 a , and expand outwardly so as to come into contact with the inside of the throttle grip 1 and supplies an urging force to the throttle grip 1 in a direction to reduce the engine speed.
  • the centrifugal clutch 4 is also provided with an eccentric weight so that vibrations are generated due to the rotation of the clutch.
  • FIG. 2 A schematic block diagram of a control system for the information device using the drive of this motor 3 is shown in FIG. 2.
  • a communication control circuit 11 supplies a transmit command to a transmit circuit 12 , and is supplied with a receive signal received by a receive circuit 13 .
  • the transmit circuit 12 receives a transmit instruction from the communication control circuit 11 and transmits a signal from the transmit antenna 12 a , while the receive circuit 13 receives a signal at the receive antenna 13 a and outputs the signal to the communication control circuit 11 .
  • Radio signals are used for communication, but it is also possible to use a light beacon or the like.
  • a signal that the receive circuit 13 has received from a moving body of another party is processed by the communication control circuit 11 , necessary information is output to traffic conditions judging means 14 which analyzes the distance from the moving body of the other part etc., and judges what stage the traffic conditions are at.
  • This judgement result is output to the display 16 and the motor control means 15 .
  • the motor control means 15 judges whether or not it is necessary to decelerate, and the drive of the motor 3 of the throttle grip 1 is controlled.
  • step 1 it is judged whether or not there is a receive signal (step 1 ), and when there is no receive signal this routine is exited and a return is executed to await a receive signal.
  • step 2 traffic is judged from the received information and it is judged, from a judgement result as to what stage the traffic conditions have reached, whether or not it is necessary to decelerate.
  • step 4 If it is judged that it is necessary to decelerate the program advances to step 4 and the motor 3 is driven, while if it is judged that deceleration is not necessary step 4 is skipped, this routine is exited and the motor 3 is not driven.
  • the driver feels the warning with his hands caused by the spring force of the throttle grip 1 and the vibration and it is reliably recognized, and it is possible to prevent the failure to recognize the warning.
  • a deceleration operation carried out by the driver is preferably an operation following the direction in which the spring force acts, and so there is no failure with respect to the judgment or operation.
  • the judgement result from the traffic conditions judging means 14 is also output to the display 16 , which means that in situations requiring an urgent display such as providing a flashing display lamp the fact that it is necessary to decelerate is also made visually recognizable.
  • the motor control means 15 varies the rotational speed of the motor 3 according to the judgement result from the traffic conditions judging means 14 .
  • the spring force acting on the throttle grip 1 is increased by rotating at a high speed, while where only a degree of urgency is required the spring force is made a suitable force by rotating at an intermediate speed, and in this way the importance of the information can also be conveyed to the driver.
  • the structure is such that a spring force acts directly on the throttle grip 1 , but it is also possible to have such an arrangement that a throttle cable connected to the throttle grip is urged in a direction of throttle closing.
  • a structure having a clutch attachment disk could be provided on a throttle pulley attached to a carburetor or fuel injection assembly around which the other end of the throttle cable extending from the throttle grip is wound. In this way, a rotation force would be generated by driving the motor.
  • the rotational force that controlled the disk causes the throttle cable to be pulled in such a direction that the throttle is closed.
  • the throttle grip is urged via the throttle cable in a direction to cause deceleration of the vehicle, information is conveyed to the hand of the rider holding the throttle grip, so there is no failure to recognize the information and a manual operation is prompted.
  • an air cylinder is attached so as to urge an accelerator pedal in a returning direction, and the air cylinder is connected a compressor via a regulator.
  • the air cylinder is activated, the accelerator pedal is forced in a returning direction, information indicating that there is a need to decelerate is conveyed to the driver's foot that is placed on the accelerator pedal, and deceleration is prompted.
  • the regulator is made to operate so that a fixed urging force is applied to the accelerator pedal regardless of the extent to which the throttle is open.
  • the pressing of his foot is preferably relaxed following an urging force in a direction of returning the accelerator pedal, and it is possible to prevent failures with respect to the judgment or operation and to reduce the overall response time.
  • a steering wheel is vibrated in a direction of the rotational axis using a vibrator or the like, and thus information is also conveyed to the driver's hands.
  • a throttle lever is provided close to a grip of the steering wheel so as to be operated using a thumb, but it is also possible to have such a structure that an urging force is caused to act on the throttle lever and vibrations are supplied.
